UNITED STATES PATENT OFFICE,

Specification of Letters Patent.

Patented March 27, 1906.

Application filed September 16, 1902- Serial No. 123,563.

To all whom, it may concern:

Be it known that I, JOSEPH A. JOHNSTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,have invented a certain new and use ful Improvement in Self-Closing Basin-Cocks, of which the following is a specification.

My invention relates to self-closing cooks for basins, sinks, and the like, and has for its object to provide means whereby a basincock, particularly a self-closing basin-cock, may be adapted to operate without the need of packing about the stem. One form of my invention is illustrated in the accompanying drawings, which is intended to be in a certain sense diagrammatic and illustrative of the general features of my device. Some of these features may be altered without altering the others, and some may be used without using the others, and they may any or all of them be applied to basin-cocks differing materially in construction from that here shown; but I have illustrated in the drawings sufficient to present the matter.

Figure 1 is a vertical section. Figs. 2, 3, and 4 are details.

Like parts are indicated by the same letter in all of the figures.

A is the basin-body, through which passes the tube-like part A, having the flange A above and the nut A below, whereby the tube-like part is clamped to the stand.

A is the pipe, through which the water is led to the cock in the direction indicated by the arrow.

A is a screw-fitted coupling having the lip A to engage the shoulder A on the upper end of the pipe A By rotating the coup ling, which travels upon the screw-threaded part A of the tube, the tube and the inleading pipe are brought firmly together.

B is an upper chamber, shaped in any desired manner and preferably screw-threaded at B to receive the screw-fitted portion of the cock-body B This cook-body is provided with a central guide-piece B shaped as shown and providing a primary waterway B and a secondary waterway B. This guide also serves as a guide for the valve-rod B, on the lower end of which is screwed the ball-valve B by means of the nuts B and B on the lower screw-threaded end B of the rod.

C is a deflector in the shape of a thin diaphragm, preferably downwardly bent, as indicated, and forming therefor an upper chamber 0, continuous with and opening into the secondary waterway B and a third waterway G which passes above the guide B and opens into the primary waterway B The rod B is also guided by the deflector O.

D is a diaphragm in the upper part of the valve-body, through which the rod B passes and by which it is guided and formed between the lower part of this diaphragm and the inner upper surface of the projecting part D, and above the deflector O is formed the drip-waterway D D is the discharge-pipe, which projects from the part D, which is in this case integral with the body of the cock.

In the upper part of the body of the cook is formed a chamber E, which contains a spiral spring E, the upper portion of which bears against the head or nut E on the rod B and the lower portion of which bears upon the bottom of such chamber. This chamber has an outer upper valve-like seat E to receive the lower portion of the disk E when the latter has descended to its lowest point.

F is a cup-like piece screw-threaded at F, so as to be received on the outer screwthreaded portion of the valve body which forms the spring-chamber. It is provided with an aperture F through which projects the handle-rod F on which is the handle F the parts being perfectly held together by the set-bolt F The disk E is attached to the handle-rod F It is beveled off at the sides F F, so as to form a sort of cam-surface, and on the inner upper surface of the cup-like portion are formed correspondingly-beveled surfaces F F The sets of the beveled surfaces are laid to each other, so that when the handle is turned and the disks are turned with it the beveled surfaces engage each other and travel, the handle and disk moving inwardly and compressing the spring E until the inner face of the disk E engages the valve-like portion E By this action the rod is forced inwardly and the valve opened, as hereinafter explained.

As previously stated, I do not wish to be limited to the process, forms, and construction shown here.

I will now describe my invention to indicate the functions of its several parts.

When the parts are at rest, they are in the position indicated in Fig. 1, and no water is flowing. If now the handle be turned, the two sets of beveled faces will engage and flected by the deflector downwardly into the current passing from the primary waterway,

travel upon each other and the handle and its rod will move downwardly. This action, however, takes place against the spring E and tends to compress it and to force the rod B and the valve B downwardly or inwardly. This action is continued until the lower face of the disk E is brought firmly into contact with the valve-like seat E and here the parts may be held by the hand. If the hand is released, the action of the spring will immediately force the parts back into the position shown in Fig. 1. As long as the hand is held in this position the water is free to flow, and it will flow in the following manner: A portion of the stream will take the shortest path to the outlet or through the primary waterway B. This will produce a suction somewhat like the action of an injector through the third waterway C and tend to draw whatever water there may be in that passage-way, along with the water flowing through the primary waterway, out through the discharge. When the valve is first opened, a certain amount of water will pass through the secondary waterway B directly up into the pocket or recess C, and here it is dethird waterway. The result of these sev eral actions or tendencies is to reduce the pressure on the water at the point where the stems or rods pass through the deflector, and there is little, if any, tendency for the water to pass through the opening and about such rod. This action is facilitated, first, by the suction or injector-like action of the water passing through the primary waterway; second, by the action of the pocket 0, which destroys the velocity of the water and turns it back toward the outlet, and, third, by the downwardly-inclined position of the deflector. Any one of these features might be omitted or modified and less than all of them could be used to more or less effectually bring about the desired result. Whatever water passes through the opening about the rod D is received into the drip-waterway, and here again it tends to pass out through the discharge, first, as a result of the suction of the and, second, as a result of the downwardlyinclined deflector along which this water tends naturally to flow. Such pressure as may exist in this passage, if strong enough to force the water up, will cause it to pass along the rod D into the spring-chamber; but it cannot pass out of the spring-chamber, because the face of the disk E is held in firm engagement with the valve-like seat E and thus the valve by its own action is normally firmly seated at one end when open at the other. This action of itself might be sufficient to prevent the discharge of the water near the handle, but in cooperation with the other devices which I have described is very effectual to that end. i l

7 For convenience I have called the valve B the supply valve and the valve construction of the parts E and E the cutoff valve.
